Switchgear SFL type, voltage level up to 36 kV, is in exploitation for a quite long time. It is mainly intended for erecting into industrial and distributive transformer stations and switchgears. The switchgear is specified by high degree of mechanical protection, secure blocking system, automatic functioning of flaps, reliable system for earthing of feeder-bars and possibility for bus bars earthing, etc.
For already delivered switchgear SFL type, there is a possibility to replace an existing SF6 circuit breaker by vacuum one, upon a special request. The modified switchgear, i.e. with vacuum insulation, is SFLV type.
